• Save money on energy bills: After you install energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll use less energy to heat or cool your house.
• Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
• Decrease your carbon footprint: By using less energy after switching to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Chattanooga

Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

Generally, Chattanooga homeowners can expect their replacement window installations to range from $250 to $1,200. The average cost is at around $600. How much it will cost depends on several factors, including type, number of windows, size, the location of your home, material and more.

Bear in mind that energy-efficient windows may come at a higher price tag, but Energy Star predicts the upgrade will save you between $101 and $583 per year when replacing single-pane windows and between $27 and $197 per year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

We recommend requesting free quotes from several window companies to find the right windows and the company that works best for your budget.

What Services do Window Installers Offer?

When considering window replacements, in general there are two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has significant damage. Because these installations are more involved, they will increase the overall cost. Pocket installations are on the simpler end and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you should opt for a full-frame installation instead.

Your window installation company will be able to help you understand what’s best for your needs. In Chattanooga, the decision will mostly depend on the age of your home and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Chattanooga

EcoWatch reviews differ from most reviews, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:

Service Area

Since this is a guide for Chattanooga, we paid more attention to companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because they wouldn’t be able to serve homeowners in Chattanooga.

Work Quality

When picking new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand you get. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have nice feedback about their service from a certain window installation company, it won’t be featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
